Performance Data
The PM891 processor unit’s performance is approximately three times the
performance of PM864. In redundant configuration too, the execution performance
is approximately three times the performance of PM864.
The figures in Table 65 are valid if the batteries have been installed after a normal
CPU power-up, allowing for the memory backup function to be activated.

BC810 and TP857 - CEX-Bus Interconnection Unit
Key Features
• Supports redundant communication interface units.
• Supports on-line replacement of the CPU.
• External power supply.
• Supports hot swap.
Description
The BC810 unit consists of two basic parts: baseplate
(TP857) and power supply/logic board.
The baseplate is where the connectors to CEX-Bus and
the external power reside. It is grounded to the DIN-rail
through metal parts of the housing. The board also
carries the external power voting diode and fuse.
The power supply and logic board contains the +3.3 V
converter, logic, drivers for CEX-Bus interconnection
and the connector for interconnection cable.
In a fully redundant system with two interlinked BC810
and primary/backup CPU pair, the BC810 support
online replacement of the CPU baseplate without
disturbing the CEX traffic.
If the BC810 has to be replaced, all traffic to the
connected CEX segment are stopped.
